It's like the people of the world are strangers to each other. Pass by and you'll find no wave, no smile, no hello.
They've got their hands full. With their phones and their antisocial, with their earphones that clog their ears, blocking them from the world. Just the way they like it. With their makeup, covering everything about them. Even their smile, even their eyes that once connected, even their face they no longer want seen.
They got no time for others. They spend all their days with their robots. They got no time for interaction, unless it's the kind with the Internet.
It's like every stranger in this world forgot how to be social, how to be friendly, how to be kind, how to be human.
